Many household cleaning products come in the Trigger Sprayer(KEXON) bottles, and the bottles are often designed in such a way to make it difficult to access the last bit of product. Not only that, but the nozzle can clog and the spray mechanism itself can simply stop working. Many of these problems can be rectified so you don't have to buy a new bottle of product, and you can save the empty bottle to use again.
The operation of a pump spray bottle depends on a spring-loaded plastic piston operated either by a trigger or a vertical pump mechanism. When you pull the trigger or press the pump, the piston forcibly ejects the fluid in the piston chamber through the nozzle, which is usually fitted with a screw-on adjustment cap. The piston automatically retracts after each spray, creating a vacuum in the chamber that sucks more fluid from the bottle though the tube. If your sprayer doesn't work, it's either because the nozzle is blocked, the piston seal is damaged or the inner tube isn't immersed in fluid.
If your spray bottle contains oil or anything else that can harden, such as hairspray, you may have to periodically clear the nozzle. Before you do this, unscrew the nozzle cap by turning it counterclockwise a quarter turn and try spraying it again. If the nozzle was too tight, your sprayer may now be working. If not, unscrew and remove the cap and hold it under hot, running water or immerse it in vinegar, then use a pin to poke a hole in any blockage in the nozzle itself. If your bottle contains hairspray, soak the nozzle in alcohol. You may have to unscrew the entire sprayer from the bottle and soak it in vinegar or alcohol if the blockage is severe.
